Storing values to an Array using foreach loop

My code: 

$videos_key = array();
foreach($result[$x]["videos_key"] as $videoskey => $result[$x]["videos_key"] ) 
    {
        $videos_key[$videoskey] = $result[$x]["videos_key"];
    }


print_r($videos_key);

I want to store all values inside $result[$x]["videos_key"] to $videos_key variable

But i am getting this error:

Warning: Invalid argument supplied for foreach()

That syntax you use is to split your array in key value pairs. 

$videos_key = array(
   array('id' => 1, 'value' => 'test')
);

$video_keys_out = array();

foreach($videokey as $key => $value) {
    $videos_keys_out[$key] = $value;
}

something like that. I don't know the rest of your code. So with that syntax you fetch the id and value keypair form the first array and you can work with them.
